LOCKED nXHnUsT 1VALVEQ I i Application filed. Julia's,

c'ountyo'l? 'Greene and State 1 of Missouri,

have' invented new and useful Improvef ments in'Locked Exhaustvalveaof wh ch the followingis a "specification; f L

.The object ofthisinvention istofprovide particularnieansfor locking a valve in the exhaust pipe of the fen'gine' of a motor ca r,:

so that the engine cannot be operatedfluntil the,.-lpckis';released by means of a key'and the'lvalve opened' jby.manipulation of the.

Controlling deviceof the valve;

A further object is to provide a par'ticu larifor'm of housing, orcasing, for the valve,

and to provide for the mounting thereofin: a p particular manner so that the casing cannot casing, and a securing device in theform of a cylinder lock of the Yale type, to be opened by a key before a controlling knob can be 7 located for rotating the stem and ope'ning the valve in'the exhaust pipe.

With the foregoing and otherfobjects in 'view, the invention -consists in the novel a construction and arrangement of elements hereinafterdescribed and claimed; it being" understood thatmodifications maybe made .withinthescopeof the claim, without de- 5 parting from the spirit of the invention.

- housing or casing, designated 10, and-formed Fig. 1 is a plan view ofmy lock valve. Fig. 2 is longitudinal section. I

Fig. 3, is a; side elevation with "parts i release posit on, due to the insertion ofa broken away.

In carrying out the inventiom'l providea with an upper portion 11 providing a chamber 12, for the receptionof the locking mechanism. The body portion, of the casing is provided with ab6re-13 accommodating the valve stem 14; and this. portion is provided first releasing the .portion fof the element 25 and 13 in position. 7 The locking pin 38 cooperates with the pin 39, in the usualmanner of locks o f the Yale type. Thespringfor element 38 is designatedAO, and spring plugs are shown I at' ll and 42,-1these" plugs being retained by a plug lockpinl, the latter being protected with ribs or flanges 15 to facilitate radiationf -The lower portionl? of the casing is likeg v 'Twise provided with ribs or flanges 15,; and r with a bore 18 extending at right angles tothe bore for the stem. Afiplateor; valvemember 19 is carrie'd by the stem 14: and

' lservesto close the. bore 18, .when the e af ,haustpipeiwith which the valve casing is" connected isjto be closed, in order to; prevent j the operation of the engine. A; sectionof Qthe'exhaust pipe is designated 21; and the r casing, element 17 is split as shown at 22 and isgprovided with ears 23, throughwhich bolts, such as 24, may pass," for clam'pingf the element 17 to the exhaustp'ipeq It will beobserved thatithe casing iormsa sub- 5 stantiallyiT-shaped member. I In order-to rotategthe stem andvalveg lp provide a knob25 havingthunib members 26; andal so having a central recess'27 1-6;. j 'ceiving the operative members of'theflock, The recess; just referred ,tois closed by a 'iinged cover 28. p f g The housing includes a flange 31 connected I by means of screws 32 to the flooring 33 off'the car.

the heads of the screws are beneath the plate cannot be reached by a screw driver. 1 i

The cylindrical body 3502f element The screws may be inserted.

through openings 34: in the element 25 when "the valve in open position, and when the valve '19 is closed and is secured bythe lock,

25'is I received by the recess or chamber in the.

member 11, and is provided with an annular, groove 36 engaged by'a spring pin 37,' the latter acting tofhold the body 35 permanentby'theplate portion or the element 25'. When the. locking elements38." 39 are in key, and the rotation of cam element 45 by cylinder G, the body 35 may be rotated manually by the knob 25, thereby imparting rotation to the stemlt throughthe connection 48, the rotation of the stemacting to open the valvelQ, sothat the exhaust pipe is free, and the engine maybe operated;

' 'What is claimed is Thecombination with connection'with apipe of a valve .in'the cas-. ing controlling'the passage of; fluid through L a valvecasingl'for 10 5" T the ;pipe,a stem for the'valve, said casing having a chamber therein and including an. i

tatable mem ber for securing the casing to, a y statlqnary element, szud means bemg 11011- removable when the lock is in engaging po- '1 sition. I

In testimony whereof I afiix my signature. 7
